Abstract (en)
A powder ratio measurement device is provided, which, in operation processes of a blast furnace, etc., can measure in real time with high accuracy the powder ratio of powder adhered to the surface of the material used as a raw material. This powder ratio measurement device 12, which measures the powder ratio of a powder adhered to the surface of a substance 26, is provided with a lighting device 18 which illuminates the substance 26, a spectroscopic device 16 which splits the light reflected from the substance 26 and measures the spectral reflectance thereof, and a calculation device 22 which, of the spectral reflectance at each position on the surface of the substance measured by the spectroscopic device 16, uses at least the spectral reflectance of the region where the powder is adhered, calculates a value corresponding to the surface area of the region to which the powder is adhered, and calculates the powder ratio on the basis of said calculated value.
